We’d like to share our passion and expertise for diamonds with you, which is why we’ve created the Blesq diamonds blog – read on for gripping tales and exciting news about the most precious gemstone on Earth.
Diamonds are, chemically speaking, pressed carbon, made of formula C. Carbon is better known to us in combination with oxygen, which carries the chemical formula O2. Carbon and oxygen make up CO2 (carbon dioxide), which occurs, for example, when we exhale air, or in exhaust gas. However, carbon alone is not enough to create a diamond. For this purpose, high pressure and high temperatures must act upon the carbon in order to turn it into a solid crystal lattice structure. It needs at least 100 kilobars and 1000° C to change the carbon to form a diamond.
These circumstances are most likely found in the mantle. This is the thickest of the three layers of earth and is located between the earth’s crust and core. At a depth of 150 – 660 km below the surface of the earth, diamonds are created from carbon, pressure and heat. This means that around 250 tons of earth have to be moved, in order to produce a 0.2 gram diamond. An incredible effort for such a small stone.
At Blesq you will find selected diamonds that have been sustainably promoted and fairly traded.
